MSSL ORIGINS
Space science in Britain was initiated and the foundations for its
development were laid very largely by one man, the late Sir Harrie
Massey who was Professor of Physics and Head of the Department of
Physics at University College London from 1950 to 1975.
Sir Harrie Massie was asked by an official of the Ministry of Supply in
May 1953 whether he would be interested in using rockets available
from the Ministry for scientific research.
R.L.F. Boyd, a lecturer in the department who was carrying out
experimental research work on rates of electronic and ionic collision
processes in gases, using newly-developed probe methods, was
particularly enthusiastic about the opportunity, and thereafter he led the
UCL research effort.
It was from these beginnings that there grew up at University College
London a space research group which, 13 years later, became
the Mullard Space Science Laboratory.

HOLMBURY HOUSE
Early in 1965 the electronics firm Mullard Ltd offered to donate to UCL
funds for the purchase of premises which could be converted into a
space science laboratory.
After an intensive search, at a time when suitable premises were hard to
find, Prof. Boyd found Holmbury House. Its previous owners included
the Hon. A.E Guinness who lived here in the 1930s and 1940s.
UCL took possession in 1965 and, as the alterations necessary for the
conversion to a laboratory were completed during 1966, the building
came progressively into use.
The Mullard Space Science Laboratory was opened formally on 3rd May
1967 by Dr F. E. Jones, then Managing Director of Mullard Ltd.

UCL MISSION STATEMENT
THE VISION: FAME THROUGH EXCELLENCE
Specifically UCL intends:

To be and to be acknowledged as, one of the greatest
metropolitan Universities in the world, serving local and
international needs.
 To be and to be recognised as, a world leader in teaching,
scholarship and research across the sciences and the arts.
 To be in the forefront in tackling mankind's environmental,
communication and health care problems.

To continue its founders' vision by providing educational
opportunities of the highest quality to all, regardless of
background.

CONFIGURATION MANAGEMENT
A discipline applying technical and administrative
direction and surveillance to do the following:
1. Identify and document the functional and physical
characteristics of configurable items(CI)
2. Control changes to the CI and their documentation
3. Record and report change processing and
implementation status
4. Audit CI to verify conformance to their documentation
and other contract requirements

SOFTWARE QUALITY ASSURANCE - 1
Requirements
– A software requirements definition for the UVOT ICU has
been produced (MSSL/SWT-UVOT/SP/001.01)
Architecture
– The software architecture/design will be guided by ESA
software engineering standards (ESA-PSS-05-0 issue 2)
and will be available after delivery
Design reviews
– Formal QA shall only be performed on software that
interfaces to the spacecraft

SOFTWARE QUALITY ASSURANCE - 2
Verification
– The UVOT ICU/DPU software verification matrix shall
be written by the UVOT software lead (with input from
MSSL)
Configuration Control
– Configuration control has been implemented using
CVS. It will be the responsibility of MSSL up until
delivery. It shall then be transferred to PSU.
